[asterisk-users] Ports that voip hackers seem to be interested in
To any that might be interested, below is a list of ports, preceded by the frequency. Personally, I find it interesting that port 5038 is now of such interest to hackers.

[asterisk-users] PJSIP Weirdness, or just my weirdness?
Hello! Oh, wise ones, ponder with me over two of the surprises that populate the universe! I have a phone, that I sometimes cannot reach, connected via pjsip. It can call other extensions just fine, it can call out over a trunk to my cell, all is well, but getting a call? Forget it most of the time. Here is all the config relevant to that phone: [murftest12] type=aor qualify_frequency=1992 max_contacts=2 [murftest12] type=auth auth_type=userpass username=murftest12 password=SjU3 [transport-udp] type=transport protocol=udp bind=0.0.0.0:57969 [murftest12]; Cisco SPA514G mac=A4:93:4C:FE:1D:A2 type=endpoint auth=murftest12 transport=transport-udp aors=murftest12 moh_suggest=default force_rport=yes rewrite_contact=yes rtp_symmetric=yes dtmf_mode=rfc4733 disallow=all allow=ulaw ; from phonetype allow=g722 ; from phonetype allow=alaw ; from phonetype allow=alaw ; from phonetype (G.729 replaced with alaw) direct_media=no context=phone rtp_timeout=120 set_var=__phoneid=12 set_var=__contacttypeid=4 set_var=__phonelineid=78 callerid="Steve Murphy" <101> call_group=2 pickup_group=2 mailboxes=101@murftest language=en send_rpid=yes send_pai=yes OK, that completes the config (I hope). Now, when I run "pjsip show endpoints, I get: SFO02-HostedPBXPJSip-Dev03*CLI> pjsip show endpoints Endpoint: I/OAuth: Aor: Contact: <RTT(ms)..> Transport: Identify: Match: Channel: <Time(sec)> Exten: CLCID: === == Endpoint: murftest12/101 Not in use0 of inf InAuth: murftest12/murftest12 Aor: murftest12 2 Contact: murftest12/sip:murftest12@67.215.23.186:54 171a08228b Unavail 0.000 Contact: murftest12/sip:murftest12@67.215.23.186:21 d9a15f4e35 Avail50.514 Transport: transport-udp udp 0 0 0.0.0.0:57969 Note that there are TWO Contact: entries! one Avail, the other Unavail... the show endpoints doesn't display all the URL, but the show contacts does: Contact: murftest12/sip:murftest12@67.215.23.186:21800 d9a15f4e35 Avail50.514 Contact: murftest12/sip:murftest12@67.215.23.186:54004 171a08228b Unavail 0.000 None of my other phones have two contacts listed and this phone, a cisco-spa-514, has just one sip account... The trouble is, when I try to call it sometimes the INVITE is directed to the "Unavail" entry, and the call never completes. The phone doesn't even ring then. Any ideas? I tried to get the "Unavail" entry out... I removed it from the db, I rebooted the phone, restarted asterisk, and it is still there. MYSTERY #2: The above cisco-spa, when it calls out over the trunk, all is well, wonderful 2-way audio. But when I do the same operation from my yealink phones, I get my cell with one-way audio. It's a classic NAT situation: the phone system is in a droplet at digital ocean, but my phones are here at home behind a NAT. I see only 3 NAT related options: force_rport rtp_symmetric rewrite_contact and I set them all to "yes", and they can call each other, but as explained, in dialing out thru a trunk, the yealinks get one-way audio... Any more NAT options? many thanks... murf -- Steve Murphy ✉ murf at parsetree dot com -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Join the Asterisk Community at the 13th AstriCon, September 27-29, 2016 http://www.asterisk.org/community/astricon-user-conference New to Asterisk?

[asterisk-users] Interesting new hack attack
In the past little while, we've seen a wave of attacks on asterisk, via the provisioning. It goes something like this: A. scan for IP phones on the internet, either via spotting something on port 5060, or via the port 80 web interface for the phone. Or, use web sites that scan the internet, and classify the machines, to make your work shorter. B. Once you get into the web GUI, get the URL for provisioning. I haven't checked yet... do any phones actually allow you to set this, or do any display the current value? And, finally, how many phones publish their own MAC address in the GUI? Or, can you suck this out of the returned IP packets? C. Given the URL and the mac, fetch the phones provisioning info, including it's sip account info. Use to best advantage. D. Going further, set up a brute-force probe algorithm, to probe all possible mac addresses for a given phone manufacturer, via http requests. After all, those provisioning web servers are fast and efficient, aren't they? Collect all possible mac addresses and grab the provisioning, and now you have a LOT of sip accounts. Use to best advantage. And, professional hacking organizations seem to also follow these rules: a. wait several months for any history of the above activities to roll off the log files. Treat your phone systems like fine wine vintage. b. Use multiple (hundreds/thousands) of machines scattered over the earth to carry out the above probes, and also to use the accounts for generating international calls. In general, using the SIP account info gleaned from these kinds of efforts is a bit problematic. You see, to effectively use your phone system to place calls, they will have to set up their own phone system to act like a phone, and register to the phone system, and then initiate calls. Trouble is, your phone is usually already registered, but can be bumped off. Your phone will re-register at intervals and bump the hackers, who will again register and bump your phone. This little game of king of the hill may show up in your Asterisk logs. So, these defenses can be employed to stop/ameliorate such hacking efforts: 1. Keep your phones behind a firewall. Travellers, beware! Never leave the default login info of the phone at default! 2. Never use the default provisioning URL for the phone, with it's default URL or password. 3. Use fail2ban, ossec, whatever to stymie any brute force mac address searches. 4. Use your firewalls to restrict IP's that can access web, ftp, etc, for provisioning to just those IP's needed to allow your phones to provision. 5. Keep your logs for a couple years. 6. Change your phone SIP acct passwords now, if you haven't implemented the above precautions yet. If I missed a previous post on this, forgive me. Just thought you-all might appreciate a heads-up. murf -- Steve Murphy ParseTree Corporation 57 Lane 17 Cody, WY 82414 ✉ murf at parsetree dot com ☎ 307-899-5535 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Use iptables to allow packets from your legitimate users, block everybody else. If you are dealing with a mobile user base or an extensive geographic area, at least block the countries where you do not expect traffic -- North Korea, China, xxxistan, etc. Drop these at the front door (90% of the problem) and use fail2ban to pick off the rest. I see a problem here; firstly that it is no longer so simple to determine the IP ranges of countries. Things have been fractured quite a bit; you might have to hire out a service to determine true geographic origination. Even then, if your service is a little behind, you might occasionally feel the displeasure of users unable to talk to your servers. How will you handle this, with a white-list? How much effort will you end up committing to keeping your whitelist up to date? Nextly, the well-financed operations running such probes need not use machines in their native countries. There are plenty of US-based machines that can be ( and are ) compromised. In other words, don't forget the fail2ban part! Here's another idea! How about changing your port from 5060 to something different, maybe 7067 or some other number that is not popularly being used? You'll provision your phones to use this port, and the scanners will not find you. Seems a much simpler solution... but there are some drawbacks... can anyone think of them? And will these drawbacks matter to you? And, given this solution, will the odds that a scanner might find your machine be so low, that it is not worth using something like fail2ban to override them?

[asterisk-users] SaySentence update - CALL FOR HELP
I'm not going to bore you with all the stuff I've done since November here. I put it, and some examples, in the file update1.txt in the git archive. To read it, do a git clone of https://github.com/WyoMurf/SaySentence.git I a nutshell, I've upgraded the SayScript grammar to handle expressions in the file names, upgraded the current en, fr, it, hu, and some others, to use the same approach as say.conf. Upgraded the test suite. Finished converting Asterisk trunk (mostly) to use SaySentence internally. I'll make the Asterisk Community an offer. Somebody out there, I hope, would like to have Asterisk in his/her language, which is not yet coded into Asterisk. I offer to help you, whoever you are, to develop a soundpack for your language. Here's the steps: 1. Get the en.template file in my github project. Copy it to the translation/your lang_locale example: rw_RW 2. Get the scripts that go with the trunk version for the sound files. (That's easy, just download any english core sound file set for Asterisk. It's in there, with the ending of .txt.) 3. Translate the scripts for the various files. These are really a mixture of full sentences, and phrases (parts of a sentence). 4. Now, go to the translation file, with your scripts. Look for the non-trivial sentences, which usually involve stuff like '%' variable references, and more than one sound file. See if the sentence parts fit together acceptably. If not, rearrange under the [format] header for that utterance. Plan new files with corresponding sentence parts if necessary. 5. Now, Plan out the way your numbers, ordinal and cardinal, are spoken, and how the money for your locale is spoken. I will help you (for free) to generate a set of SayScripts for your language. We'll have to deal with issues like gender, or who-knows-what-else! 6. Run a bunch of tests to make sure the numbers, etc are generated properly. 7. Find a friend with a nice voice, and hand them the 400+ file scripts. If you can't find one, or can't afford one, find a quiet room, and record them yourself, as best you can. Edit the recording into separate files. Clean them the best you can. Get them in the best, highest quality format you can. 44+ kiloherz wav pcm files if possible. I'll get them into a good format; Asterisk trunk can handle sln32 or higher file formats. My intention is that the sound files in soundpacks will be a single best choice format. When installing sound packs, the files can be converted into any combination of formats you wish. We can use Asterisk itself to convert the files, or sox. All I know is that the higher quality the source sounds are, the better off you'll be converting them. 8. We'll form your sound files, scripts, and SayScripts into a single Sound Pack. Possibly the first one ever. I'll have to get busy and write some scripts to build sound-packs, and some scripts to install them. I'd like to help with at least one new language, if possible, to see what can be done to smooth the process. Interested?

[asterisk-users] A Question about Management/Control Protocol Licensing
I see the following paragraph in the Asterisk trunk LICENSE file: In addition, Asterisk implements two management/control protocols: the Asterisk Manager Interface (AMI) and the Asterisk Gateway Interface (AGI). It is our belief that applications using these protocols to manage or control an Asterisk instance do not have to be licensed under the GPL or a compatible license, as we believe these protocols do not create a 'derivative work' as referred to in the GPL. However, should any court or other judiciary body find that these protocols do fall under the terms of the GPL, then we hereby grant you a license to use these protocols in combination with Asterisk in external applications licensed under any license you wish. This probably originated some years ago, and I wonder if Digium or the Asterisk community might consider adding the OTHER management/control protocols to this list: ARI, and the ExternalIVR interface.

[asterisk-users] Language Coverage in Asterisk
I see that Asterisk distributes soundsets for English/English-AU/Spanish/French, and Russian. There is code for several other languages inside Asterisk; how does one obtain the other soundsets? Also, I noted that the source sound files don't seem to be publicly available for the sound sets that Asterisk distributes. I would assume that the source sounds are all 44khz (or more) cd quality sounds, probably in pcm wave format, maybe even in stereo. Are these source sound sets indeed withheld from the public?

What kind of device are you using? Dahdi? SIP? You can use the rtp set debug to see if the DTMF is coming thru; look at your channel config, there may be something there that might prevent DTMF. Same with the phone settings.

[asterisk-users] SaySentence/SoundPack Proposal
Hello-- Boy, it's been a long time since I posted to the user mailing list! Pardon me, I've posted this to dev also, but I thought the general users should also be aware of this. I'd like to announce a proposal to the Asterisk Community, that I introduced at Astridevcon last month. It is a new API for playing sound files (mainly speech). A pdf describing the Proposal in some detail is at: http://www.gmvoices.com/downloads/steve/sayscripts.pdf The end goal is to reduce the cost of making sound sets for new languages, IVR's, etc, and to extend the capabilities of the Say mechanism to allow more natural sound sets for Asterisk. It is a mix of GNU gettext features, a new way of thinking about, and how to organize playing sound files in asterisk, extends ideas introduced by Tilghman Lesher and Luigi Rizzo, and is meant to replace the expansive code in say.c, app_voicemail.c and other places. It is also meant to simplify, in many ways, how to play sound files in general. It moves the code in Asterisk, out into the soundpack. Now, the soundpack will contain everything necessary to play sounds at a high level thru Asterisk. It is hoped that SoundPacks can be standardized, so that they will not only work on Asterisk, but other phone systems as well. As a first pass at implementing the SaySentence/SoundPack, I have produced a SaySentence server in Java. I have diffs against asterisk-trunk that converts a large chunk of usage into the new regime, and uses the server to generate the file lists. I have begun a conversion to C, which will ultimately replace the Java server with an embedded library to provide the same functionality. I have tested the code in the dialplan and via app_voicemail. All this code is provided, with build instructions, via my project at github: https://github.com/WyoMurf/SaySentence.git I am looking for help from developers and translators. If you are interested in knowing more, have objections, ideas, etc, let me know! murf -- Steve Murphy ParseTree Corporation 57 Lane 17 Cody, WY 82414 ✉ m...@parsetree.com ☎ 307-899-5535 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Play subscriber's recorded messages

I have recorded a message, and I can see it saved on the system, but still Asterisk keeps playing the original message... Is there something I can add to let the subscriber plays his recorded message if he has a one? I couldn't find a clear way in the wiki about that! Also can I go more to play specific messages depending on the day/time, a specific message for the holidays for example? Thanks. Asmaa-- It's not entirely clear to me what the problem is, but it appears that you have recorded an unavailable message via the voicemail (comedian) app, and are not getting that message played back when someone is routed to voicemail for that user. If this is indeed the problem, you didn't show the Voicemail() app call in your dialplan. Don't forget to add the 'u' option to the call for unavailable: exten = 7001,n.Voicemail(7001,u) to actually get the voicemail unavailable message to be played. Use 'b' for busy. In asterisk, you can type core show application voicemail to get the documentation for that app. As to the message you can play, voicemail has absolutely no mechanisms to allow you to apply some time schedules to your IVR prompts. But, if you null out the plain/busy/unavail messages, you can use the dialplan to set up any kind of opening messages you want, and in that way, you can do almost anything imaginable. When you get done playing whatever you want, then call the Voicemail() app for that user. If you use a few milliseconds of silence in all the recorded message files, then you have effectively overridden its built-in sound file playing with your own introductory messages instead. murf -- Steve Murphy -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Followme Killing Asterisk

Hi Guys,
this has been a weekend destroyer for me. I've struggled this all day and
most of today.
From your discussion below, it sounds like the real problem is the Asterisk
crashing.
So, as a first step to solving **that** problem, make sure asterisk is
compiled with debug
flags, dumps another core file, and then you do the gdb asterisk
corefilename, and
get a stack trace. That should give us some idea of what happened.
I have a fairly simple Followme sequence in place to see how it works
before I get into the complex scenarios.

same = n, Dial(SIP/GW-1/${EXTEN})
followme.conf
[TestFollow]
context = Followme-Dialout

The call goes out, and rings my first phone. If I answer it, the Asterisk
core dumps, the calls stay up!

I have been playing with Local channels over the weekend, and as cool as
they sound, they have caused me nothing but pain. Once again, following the
console log, I notice that Followme indeed uses Local channel to make these
calls and returns control when the call times out etc.
The ONLY time it gets anywhere is if I use the 'l' option with Followme
application.
In that case, the call connect and I can have a conversation but the
minute the remote party hangs up, asterisk dumps core again.
it may be something to do with the after return to handle next steps but
what are they supposed to be? I don't want anything to happen like go to VM
or anything.
Have tried this with 10.3.0 and 10.11.1. I noticed new changes have been
made in v11...but this should work
How does this work?? Do I need fancy options with the Dial command doing
GoSub and what not? and Why does it insist on playing all these prompts I
have commented them all out from followme.conf, but it's still looking to
play them
Thanks in advance

[asterisk-users] INVITE retransmission by 1.8...
I have a site that moved to the latest 1.8 revision, and began to have problems with phones in far away places (South America, and the MidEast). What I see is that when a Dial() is issued, the sip channel driver sends out an INVITE to the phone. Very soon thereafter, Asterisk retransmits the INVITE. The phone sends back a 100 Trying, and then, usually, a 400 response. I may be misinterpreting what I see, but I *think* that the response from the phone is delayed just enough to invoke the retransmission. The phone responds to the second invite with a 400 code, which Asterisk interprets as an error, and the call immediately goes into hangup. Has anyone else seen this? It doesn't happen all the time, and only with certain phones. It comes and goes, but when it comes, phones become unreachable. It seems to be in this state the majority of the time for certain phones. While most phones seem far away, some are in Florida. We replaced the 1.8 version of Asterisk with a 1.6.2 version, and the issue has gone away. I know, I know, I could give more detail, fill out a bug report, but this is the early stages. I may be misinterpreting what I'm seeing. Anyone else seen this sort of thing? Any words of wisdom? murf -- Steve Murphy ParseTree Corporation -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] dialplan is not finding my number asterisk 1.8.3
Oh, you are *not* going to like this, but you have a few different paths: 1. If the dialplan stuff is not really a memory corruption, but some sort of unplanned, but maybe accidentally programmed thing, either by you or something in the asterisk code, then: a. compile asterisk for debug. You can get in the menuselect stuff and make sure the debug compile options are turned on. Install it. b. Shut down asterisk c. fire it back up, under gdb: gdb full path to asterisk br ast_context_remove_extension_callerid2 comm 1 where c end run normal arguments to asterisk Then use asterisk as normal and wait for the problem to re-occur. Look to see if any calls to ast_context_remove_extension_callerid2 occurred (they will occur with dial reloads-- lots of them). You'll have to search carefully! The gdb messages could be buried in your console output. If the problem reoccurs, but you didn't see any calls to ast_context_remove_extension_callerid2, then it could be assumed that you are suffering some sort of memory corruption. Where it dies, or things start looking strange, may not indicate where or why the corruption is happening. In such a case, it really gets tricky to debug. Then we might resort to stuff like dmalloc, and others, to help spot where/when corruption occurs.

If you know the number of digits, and it is fixed, then you could use _011870XXX or similar to avoid the timeout, and begin the Goto immediately on reception of the final digit. The X in the second set will match just one digit, and the Goto will be be executed.

Thanks Nikhil Nikhil-- Yes, there is a problem with CDR's in asterisk. There is a bug filed against the problem, but no practical solution for it. The cure: use the CEL interface instead, and generate your own CDR's (or whatever else you could bill from [it doesn't *have* to be CDRs]) The cause of the problem: An interesting combination of 3 operations being performed on channels, namely masquerading, and forming local channels; add to that the hardwired 'roles' that channels are given (channel, and peer), and the final knockout: CDRs are stored on channels. The above 3 operations affect CDR's because parking and transfers can change the role that a channel plays (chan to peer or vice-versa); Transfers and parking involve the masquerading, and sometimes local channels-- both these operations involve duplicating a channel. CDR's are meant for the channel playing the channel role, and CDRs on channels playing the peer role are tossed out. Transfers turn the above into a complex mush in which the results vary depending on who transfers who, who is calling, and who is called, etc. Because the CDR's are stored on the channels themselves, they pass thru many filters and operations that vary based on the roles they play and the operations performed, which can change in subtle ways from release to release, from one bugfix to another, even. So, the best way to get around all this is to get the CDRs out of the channels, And to do that, you either use CEL, or you build your own event tracking mechanism, using whatever means available (I've seen folks use the manager event reports with their own logic in perl, or php, or whatever to do the parsing and storage). Then, you either turn the events into your own billing mechanism, or you generate CDR's to fit into your currently existing billing mechanism. Doing this right and making it dependable is not an overnight sort of thing. I proposed a CDR generating backend for CEL (which I haven't completed yet). I even started it, but got layed off before I could finish it. I've generated a spec for CEL-CDR generation, involving something I call simple CDRs.This doc has been evolving with time, and needs to be updated. I previously described complex CDR's in the spec that provided more fine-grained event logging in CDR format, but I've convinced myself that the complex stuff can also be done via the simple method, and so I'm about half way thru the spec, expunging the complex stuff. All my examples have to be changed -- If you are interested in looking at my spec, you can: svn co http://svn.digium.com/svn/asterisk/team/murf/RFCs and look at the pdf there in that directory. murf Steve Murphy ParseTree Corp. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Thanks Nikhil I can tell you that back in 2005 I set up a complete residential/business VOIP ITSP that was using just the Asterisk CDRs to track billing. As long as you setup your billing, I see now reason wh Oh, and by the way, Sherwood is correct; you can ignore everything I wrote previously, IF you don't do call transfers, and you don't park calls. And even if you do a small amount of that, as long as no one forwards an incoming call to some international destination, you'll probably be OK with CDR's. If you don't mind losing a little chunk of the conversation here or there, the current CDR's should be sufficient for you, and you don't have to go thru any bother. Just keep in mind that clever people can/will take advantage of the fact that everything after an incoming call is transferred is lost to billing (as an example). murf Steve Murphy ParseTree Corp. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] codec_g729a implicated in file descriptor buildup
Hello, I wonder if anyone else has noticed this. I see a pair of calls to pipe() within the codec_g729a, and suddenly, I have a leaked file descriptor that remains until asterisk dies. Now, maybe no-one sees this, mainly because I have no g729 licenses on the machines where this happens. And conversely, I haven't yet studied servers that do have licenses. Why have codec_g729a.so loaded if I don't have licenses? Well, I can install licenses on the run as needed this way, and not worry about having to install anything, or muck things up if there is a mistake. I can mod the phones and get g729 used without restarting asterisk or loading modules. On completely quiet machines, with no calls in or out, I get one descriptor per day, maybe of a daily reload or something. I haven't gotten that far in my investigations yet. Since the module isn't compiled with debug info, the best stack trace I can get is: #0 0x4d5544a0 in pipe () from /lib/libc.so.6 #1 0xb69384ce in __cxa_finalize () from /usr/lib/asterisk/modules/codec_g729a.so #2 0xae7fdae4 in ?? () #3 0xae7fcae4 in ?? () #4 0x1000 in ?? () #5 0x in ?? () The version of the g279 module is: Digium G.729A Module Version 1.6.2.0_3.1.4 (optimized for generic_32) Just now, on a very low-volume asterisk server I am monitoring, two calls just got processed. The g729a codec did a pair of pipe() calls, and voila! I have one more open file descriptor as reported by lsof. Some of my servers (which are busy, but nowhere near capacity!) will build up 100 such leaked descriptors per day, and unless I jack up the maximum number of file descriptors, those servers will have to be restarted about every 10 days, or they will eventually stop accepting calls (or making them, for that matter). Not nice. So, since there is no list of problems fixed with the current g729a module distribution, (at least, no in the README in the dist, is this a problem that is known? Is this a new problem?

What should i do? using some loopback cable maybe? Thanks in advance DD I set up two machines with T1 interfaces, and connected the two with an appropriate t1 cable. One was acting as a network (master), the other as a subscriber (slave) (for timing). wrote two dialplans, one for each machine, that would answer an incoming call on one dahdi line, and call to the next numbered line on the other machine. The other machine was similarly outfit. I'd define the extension for the first line on the t1, and call it with any phone you desire. That call will cascade into 23 separate interlinked calls. If you are clever, the last call in should dial another real phone you have on-hand. You get the picture... right? Phone A dials the exten to call the first exten on the other machine. The dialplan should use the first channel on the t1 to place a call to the first exten on the other machine. On the other machine, the incoming call on channel 1 is answered, and then a dial to the second extension on the first machine, over the 2nd t1 channel. The first machine answers, and uses the 3rd channel to call the other machine and so on till all channels are being used. The last exten answers and dials a phone (dahdi or SIP, no matter) that you pick up. Such a looped call should probably be awful, but it's going thru 23 t1 channels! If you have two t1 interaces in a single card (or two cards), then you do this on one machine. Another approach: set up equal numbers of FZO and FXS lines, and similarly loop s single call thru all the channels.This would require just one machine. Other approaches would involve running multiple threads to call an extension and then hang up and repeating this over and over again on all channels to ascertain the load placed just by call setup and tear-down. This kind of load is different than when all lines are just shoveling data back and forth. Watch your load averages, your %cpu, your swap, etc, as the tests are in full swing. murf -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] help with dialplan
Todd--
There is probably some nifty anti-infinite-recursion code in the
extensions.conf parser,
to keep asterisk from going into infinite loops trying to descend into the
right context.
In your dialplan, [remote] includes dialout1, dialout2, dialout3, and each
of those
include remote.
Straighten out that mess and maybe things might work. Just a guess, but
worth a try!

My guess is that your .wav file is NOT 8khz. The system doesn't accept anything but wav files at 8khz. Use sox to downsample to 8khz (and 1 chan), and the problems should go away. While you are at it, you could use sox to convert to the target format in a single operation. The scripts that Digium uses to take Allison's voice prompts (at 48khz) to the different formats, convert things to slin (raw) as a central format, but in my experience, the fewer steps the better. But I doubt that anyone could detect the difference in the end result... Here's what I do with CD-qual sounds to turn them into the common Asterisk formats: Assume $i is the name of the .wav file you want to convert: x=`basename $i .wav` sox -v 0.7 $i -r 16000 -c 1 -t sw $x.sln16 sox -v 0.7 $i -r 8000 -c 1 -t sw $x.raw sox -r 8000 -c 1 -t sw $x.raw -t gsm $x.gsm## OR ### sox -v 0.7 $i -r 8000 -t gsm $x.gsm sox -r 8000 -c 1 -t sw $x.raw -t ul $x.ulaw## OR ### sox -v 0.7 $i -r 8000 -t ul $x.ulaw sox -r 8000 -c 1 -t sw $x.raw -t al $x.alaw ## OR ### sox -v 0.7 $i -r 8000 -t wav $x.wav rm $x.raw y=`pwd` sudo asterisk -rx file convert $y/$i $y/$x.g722 I'm ignoring the siren g729 formats; use asterisk for those in like format, depending on your asterisk version and codecs. Allison normalizes the volume of sounds she distributes; use the -v 0.7 to bring the volume down a bit to the standard, and your sounds won't stick out against rest of Allison's existing recordings in Asterisk. Digium uses a filter program to 'heighten' the sounds a little; That's the main reason, I think, that they use the .raw format as an in-between. I've been skipping this step, as it doesn't seem critical, in which case the direct conversion is probably preferable. I suggest, that if you are converting sounds for Asterisk's sake, that you convert to all the possible formats. Disk space is cheap, and you'll squeeze a little extra performance out of Asterisk by allowing it to pick the 'best' format. Dahdi type interfaces would prefer the ulaw/alaw formats; High-def phones like Snom (and appropriate Polycoms, etc) could use the g722. Ulaw and gsm transcodings are cheap, but no transcoding is cheaper still. murf Kind regards, Jonas. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Deleting extension makes it usable?
I hope I'm correct, I don't have time to verify every bit of this, but The message [Jun 7 17:04:16] NOTICE[7422] chan_sip.c: Failed to authenticate user asterisk sip:3...@206.205.124.247 sip%3a3...@206.205.124.247 ;tag=as23bacb61 indicates the user asterisk. Do you have a sip account for asterisk? Why it would take 14 seconds and an ANSWERED dial for an unathenticated use is something to investigate! As to the more general question of how 3799 could be unexpectedly matched in the dialplan, I would respond that there are several possibilities... One is, Is the account with the weak pword removed from sip.conf? The 3799 account? Because, it looks like SIP/206.20... (you abbreviated here in the CDR you listed) is where the call is originating. b. Did you *really* get rid of all 3799 occurrences in the dialplan? What patterns do you have in the dialplan that might match 3799, after the explicit 3799 is removed? Any _ type patterns included or in the context in question? c. I uncovered a pattern matching bug, and reported it in bug https://issues.asterisk.org/view.php?id=17366 where unexpected patterns are matched. Sorry, I haven't had time to correct it myself, it's probably a simple 1-line fix, but oh, what it might take to figure out what the line should say, and where it is! d. s is the start extension, and an incoming call will tend to get routed into an s extension.

Re: [asterisk-users] file command with alaw file
Quyps-- I've noticed in general that the ulaw, alaw, gsm, slin files used and generated by asterisk do not have headers (the RIFF stuff), and asterisk is not expecting them. in general they will louse up Asterisk's ability to play the sound. They are just raw data and the extension on the file name (.gsm, or .ulaw, etc) is the only clue to the file format/contents. In general, if you need a sound file of your own making in a certain format, you can convert to most of the formats using sox in linux, but really, the best thing to do is record the source sound file in cd-quality sound WAV format, in 44 khz sampling rate, or higher, and then use sox to convert to 8khz format. Asterisk can do some of this via the file convert CLI command, ( on the asterisk cli, type help file convert). You'd have to judge for yourself if file convert tt-weasels.gsm tt-weasels.ulaw which would convert the 8khz gsm format to 8 khz ulaw, or sox -v 0.7 tt-weasels.44khz.wav -r 8000 -c 1 -t sw tt-weasels.raw; sox -r 8000 -c 1 -t sw tt-weasels.raw -t ul tt-weasels.ulaw which is the way the Asterisk sounds are produced from the the cd-quality sounds.

As I said I didn't change anything, except for making few minor changes to the firewall today and that was at Amazon firewall level and not within CentOS. What causes these bad dahdi_test values? P.S. there is only few calls load at anytime on this server. Here are few ideas: 1. I have seen complaints that as Amazon loads up its virtual machines, that neighboring VM's running on the same hardware are sucking up CPU cycles and reducing the performance of the other VM's on board. One guy was complaining that to get the same performance he got a few months ago, he has to move to a more powerful machine, which costs more . You might move up to a more expensive, faster VM and see if it helps. 2. I don't know exactly how Dahdi gets its timing, but I do know that it has two methods; one involves HIGH RES TIMERS compiled into the kernel. The other when the high-res stuff isn't included. You can decompress /proc/config.gz into a local file and look for HIGHRES to be defined. If it isn't you might try to find a kernel with it defined, and see if it helps. 3. If you are on 1.6.1 or 1.6.2 (too tired to look up which), you could try using another method of generating timing than dahdi_dummy. I suspect that they may just reflect code already in Dahdi_dummy... but this seems like something you might want to become knowledgeable about! murf Thanks On Wed, Apr 21, 2010 at 8:03 PM, Carlos Chavez cur...@telecomabmex.comwrote: On Wed, 2010-04-21 at 19:36 -0400, bruce bruce wrote: Here are result of dahdi_test: [r...@ip-10-251-123-3 ~]# dahdi_test Opened pseudo dahdi interface, measuring accuracy... 99.725% 96.018% 99.532% 91.934% 99.923% 99.923% 99.628% 99.434% -434.763% 99.239% 93.770% 99.141% 99.822% 91.232% 99.727% 93.770% 99.726% -403.227% 98.069% 98.458% 95.136% 98.749% 91.229% 87.622% 98.554% 93.282% -407.620% 94.650% 96.308% 98.750% 96.993% 93.478% 94.063% 93.381% 61.745% -379.400% 99.628% 99.921% 99.142% 96.797% 98.457% 99.337% 87.909% 95.141% -396.880% 99.531% 99.923% 99.921% 91.035% 96.408% 91.916% 90.255% -402.153% 81.079% 74.534% 96.212% What can one tell from these?

Re: [asterisk-users] Being attacked by an Amazon EC2 ...
Hmmm. It would seem that it would be to Amazon's advantage to jump on this problem, because the accounts that are performing this activity are most likely purchased with stolen identities, and sooner or later the charges are going to get reversed. Either the credit card companies are going to absorb the cost, or the merchants (like Amazon) at the other end. And, after listening to merchants grumble about it, I'd assume that in the end, Amazon is going to get stiffed for the bill. On someone else's credit card, I'd imaging they have almost infinite resources; Bandwidth to burn, the best and most powerful hosts. So what if they rack up thousands of dollars? They are probably organized crime units in Romania or whatever. murf On Tue, Apr 13, 2010 at 11:21 AM, Tzafrir Cohen tzafrir.co...@xorcom.comwrote: On Tue, Apr 13, 2010 at 04:32:58PM +0200, Hans Witvliet wrote: On Tue, 2010-04-13 at 15:49 +0200, Philipp von Klitzing wrote: Hi!

OK, I went and looked thru the source. The code doing this to your CID
number is ast_shrink_phone_number(). It gets called on your cid number
and dutifully does this:
remove '(', ' ', ')', non-trailing '.' and '-' not in square brackets.
Because the . is not at the end of the pattern, it gets wiped by this
routine.
There seems little to do about it, as is. The call to
ast_shrink_phone_number()
is not optional or conditional. Apparently, asterisk is expecting plain
phone numbers
with stuff like (715) 693-4855, or 715.693.4855, and will remove the cruft
for you. That
it's preserving dashes inside of brackets (and brackets, too), means it is
expecting
to see patterns here.
So, I'd file a bug, and say that a dot in brackets should survive, too,
along with a
dash in brackets. ...that to limit dots in the cid pattern to the last
character is
not good behavior.
Because of this, I wonder if your CID should begin with an _ you'll
have to test
it out if they go and add the few lines to that routine they would need to,
to allow
dots in the pattern string. My memory is failing me and I don't have enough
time
to go playing in the source code.

CLI show dialplan example
[ Context 'example' created by 'pbx_config' ]
'test.skype' (CID match *'example[]skype'*) = 1.
NoOp(nothing) [pbx_config]
2. Hangup()
[pbx_config]
As you can see the only . has been erased.
There is no problem on DID (. notations works fine), but only in CID
field.

What is the suggested replacement for an explicit Gosub() call? I use it
like this:

Gosub(blacklist,${exten},1);
...
context blacklist {
_+43900! = Hangup();
_+43910! = Hangup();

How about:
blacklist(${exten});
macro blacklist(the_exten)

switch(the_exten)
{
pattern +4390[01]: Hangup();
default: return;
}
}
You could use something like the above.
Basically, you are using the pattern matching capability to
end the call for certain extensions... so the above should
come close. If you really, really want to keep your gosub call,
then you can, you'll just have to ignore the warnings, iirc.
murf
In 1.6, AEL macro() is implemented using Gosub(), so you can use it as a
direct replacement. This is listed in the CHANGES file.
Hi Kevin!
I know that AEL macro does not use Macro() anymore, but Gosub(). But
does that imply the other way round too?
Using an AEL macro (which is implemented as Gosub) instead of a Gosub
does not work as the target is a context, not a macro which is
implemented as pseudo context with an 's' extension.
I do not see a way to implement the above dialplan using an AEL macro.
Do I miss something?

Very true, but the added syntax would not replace '.'. And they mean two
different things. X\{1-\} would mean one or more numbers, . means
any number of any character.
Heck, besides N\{2-4\}, Z\{3-7\}, I guess we could even do .\{2-100\}, which
could mean 'match everything at the end of the string, but only if there's 2
to
100 of them', or something like that. Whatever is the most handy.
Another thing that I think would help: an equivalent of perl's \w:
something similar to 'X', but also matches letters. This is syntactic
sugar, but we need such sugar for readable dialplans.
Could be done, but it ends up getting in the way of exact matching;
right now, using X,N,Z keeps you from exact matching those characters,
(is there some escape mech in the syntax to let you say \NA\NCY? I
haven't checked). But, there's no reason we can't add other matching chars
for handy things. A = alpha chars Y = alphanum chars, G = Graphical chars,
whatever. We just have to watch those backslashes, because if we use them as
an escape to mean literals in some situations, and as a notation to mean a
special function in others, then it starts getting confusing real quick.
But all this kind of thing Could Be Done.

Leif and I had a proposal years ago for an alphaexten that used perl
regexps.
Yes, I know that many have proposed full regex and regex-like extensions
for
the dialplan patterns, but there's one big rub. The current pattern matcher
is light and
fast compared to a full regex matcher. The restrictions on constructs make
it a fairly
fast linear matcher without any loops or recursive behavior to slow it down.
We can currently use
rules to quantify the best match that makes it fairly predictable, and the
work on a
fast pattern matcher (O(log(pattern length)) instead of O((num
patterns)^2) was possible.
But, when you move to full regex approaches, you lose all those nice
properties. You'd have
to move to a 'best match first' sort of strategy, so you can move from a
O(n^2) type scenario,
and you lock yourself into an O(n^2/2) scenario. For large dialplans on a
busy system, you are
totally screwed, without any hope of improving the situation.
I tried in times past to propose a subset of regex patterns that would still
leave us with fast
pattern matching

hard to offer SOME regex syntax in patterns to help reduce the impact of
these kinds of problems.
Like using:
[incoming-from-voip]
exten = _X\{7-10\},1,Dial(${ext...@incoming-from-voip-old)
instead of :
[incoming-from-voip]
exten = XXX,1,Dial(${ext...@incoming-from-voip-old)
exten = ,1,Dial(${ext...@incoming-from-voip-old)
exten = X,1,Dial(${ext...@incoming-from-voip-old)
exten = XX,1,Dial(${ext...@incoming-from-voip-old)
I put the \'s in front of the {}'s because we probably wouldn't want to
change the
behavior of exact matching, and there's some precedent for using such stuff
in some implementations of regex, where \ matches the beginning of a word,
etc.
and, of course there would be the shorthand variants \{7-\} for seven or
more; \{-10\} for 1-10.
Some might argue 0-10. Whatever.
I THINK this could be implemented in both the fast pattern matcher and the
current slow one. I know it wouldn't be that bad to do in the fast pattern
matcher.
I hadn't really given the slow one (the current one) much thought.

BTW, you could add a catchall mail the sysadmin option - so when you get
a number that is not being matched you could be notified and adjust the
dialplan as needed.

To avoid extensive rewriting and fix the current issue.
That works in countries where you have fixed-length numbers.
Unfortunately, not every dialplan works that way, so that can't be a generic
advice even though it may solve your problems.
Thanks for your suggestion!

Re: [asterisk-users] How to make SpeechBackground keepplayingifutterance doesn't match our grammar
Quinn--
I would venture to guess that your problem is because you are using the
sound file streaming
mechanism at too high a level. At the app/agi level, you don't get any
control over the process.
You start the sound process, then you wait for the interrupt; it's all
neatly bundled into a single
package.
At the C level, using the machinery that Asterisk uses, you use these calls:
res = ast_streamfile(chan, Filename, chan-language);
if (res2) { failure_code(); }
else {
ast_autoservice_start(chan); /* keep those packets running out to chan
*/
}
/* put code here to process the stuff from voice recognition s/w until you
get what
you want, or time out, or whatever */
if (!res2) {
ast_stopstream(chan);
ast_autoservice_stop(chan);
}
The code above pretty much supposes that the file will play longer than it
will take to get some outcome
from the VR stuff; but no matter, if it runs clear to the end, it will just
leave you with a dead channel.
Best to set some sort of timeout so as not to sit forever if the person at
the other end of chan is mute
or dies or something. The main thing to remem is that autoservice_start()
and streamfile() immediately
return, and do not block, and the shuffling of sound packets is handled in a
different thread. Some other
event or timeout or something needs to eat up time between the starting of
the playback and the stopping
of the playback.
Hope this helps, probably not what you were hoping for.

Re: [asterisk-users] Inserting a wait in a sip dial SOLVED (kind of)
Dave-- I remember adding a feature a long time ago for snoms, to the source code, to send dtmf out for some button press on a snom phone, in the 'outward' direction, I think to activate a feature or somesuch. (Boy, is my memory hazy!) At any rate, I was able to inject dtmf, but I had to do it in the source.

So, if you found a workaround, and it works, it won't matter how pretty it is. Magic is Magic.

I’m pretty sure that attended transfer is a “features” function, not a
dialplan one.
Yes, you're right but do you think there's such a big difference between
both that it shouldn't be easy or even possible to add support of attended
transfer in dialplan ?
What I have in my mind is this :
Today, Dial application M or U options allows macro execution when caller
and callee are connected.
What if this same macro could be also launched during some later events
(like attended transfer) ?
With features.conf, you could then specify :
- how lo launch an attended transfer (which key to type as today),
- if a given feature (attended transfer, parking, ...) should be
supported by Dial macro option (for compatibilty, default could be set to
none)
and with extension.conf, you could specify :
- which specific treatment (sending UserEvents, launching an external
program, ...) to apply
In this puzzle, if Asterisk could support a few more standard variables
like ATTENDED_TRANSFERER ATTENDED_TRANSFER_TARGET, you would everything to
define and run attended transfers specific logic :
exten = 123,1,Dial(SIP/123,M(mymacro^arg1^arg2)) ; mymacro is launched
upon connection and specified (in features.conf) events
[macro-mymacro]
GotoIf(x${ATTENDED_TRANSFERER},
What about that ?
Olivier--
This is actually not a bad idea.Why single out just the Attended xfer? Why
would you treat
attended xfers differently than blind xfers? Just curious.
Also, calling just one macro for all features seems a bit restricted. Why
not allow the features.conf
to specify which macro/gosub to call, for each feature? Dial is already
overloaded with options,
anything that could be offloaded would probably be desirable. Plus, calls
that were not initiated by
a dialplan Dial() invocation might not be able to provide that option.
Another question: what do you need this functionality to *do*? It could be
that there is an already
existing functionality that you could exploit to get the same results?

Hi,
I'm using asterisk 1.6.1 and AEL2.
I'm trying to find the best way to write my own custom functions ?
At the moment, I'm using this pattern (extensions.ael) :
context foo {
123 = {
myfunc(123456);
NoOp(${GOSUB_RETVAL});
};
macro myfunc (arg) {
Return (${arg});
}
1. First, I keep getting warnings like
Warning: file /etc/asterisk/extensions.ael, line 446-446: application call
to Return affects flow of control, and needs to be re-written using AEL if,
while, goto, etc. keywords instead!
and I would like to get rid of them.
This is easily done. Return() is calling the Return application; 'return',
however, is the keyword the AEL uses. Note the lack of a capital R at the
beginning of
the word return. AEL is case sensitive and Return is not equal to
return.
Also note that, as a previous reply mentions, that return takes no args,
that there is a patch available to upgrade to do that.
You don't need the patch to do what the patch does, tho. But, not having
refreshed my memory on the particulars, I will say
no more!
2. Secondly, I would like not to use GOSUB_RETVAL and call a custom
function just like I'm calling other functions with statements like :
123 = {
NoOp(TOLOWER(fOo BaR));
NoOp(myfunc(123456));
};
Again, check your version of Asterisk against whether AEL uses Gosub() to
implement macros.
The AEL2 wiki page on voip-info.org (
http://voip-info.org/wiki/view/Asterisk+AEL2 ) can also
be quite helpful at times!
What would you advise me to do ?

[asterisk-users] Leg-based CDR proposal updated; Major mods
Hello! It's me again. I began a fairly large modification to my CDR proposal some weeks ago, and finally yesterday and this morning got enough accomplished to allow a commit and some peer review. Check the docs out via svn co http://svn.digium.com/svn/asterisk/team/murf/RFCs This is a directory; in it you will find: CDRfix2.rfc.doc CDRfix2.rfc.docx CDRfix2.rfc.pdf The docx version is the one I actually edit; the doc verison should be editable in both the windows and linux worlds. The PDF version is for those who just want to read it. Basically, I modified the doc to turn Leg-based CDRs into Simple CDR's with splits (both automatic and dial-plan generated). Instead of a single time line for complex conversation, broken into consecutive segments, now you have N time lines (one per participating channel). A Leg-based CDR system devolves into a Simple CDR system when all the automatic and dial-plan splitting is turned off. This makes things easier to implement and understand. At least, for me! (If I don't understand it, I doubt I can make YOU understand it!) Also, I gave uniqueID's an overhaul based on the idea of REFERENCING. I think most users have misunderstood the uniqueID field in the current CDR system, and don't see the possibilities that solid referencing would open up. I introduce the idea of uniquely identifying channel 'instances', which are what Asterisk creates when it creates a channel struct internally. The uniqueID field on the CHANNEL struct uniquely identifies that channel instance across time for a single server. (Currently). (barring masquerades). These are what are REFERENCED by my destchannel, and channel fields. I provide new fields called channel_uniqueid and dstchannel_uniqueid to reference these fields; not just the channel name (dahdi/1-1 doesn't quite suffice across time.) (But I left the old fields alone for those who prefer device info). CDR unique ID's can/will be generated for external usage, but are not available to the dialplan or apps within Asterisk. Thus, only external referencing is possible to individual CDR records. But this should be good enough, I think! This may or may not help with issues brought forward a while back by greyman and others, -- I'd appreciate hearing about it. murf -- Steve Murphy, Pres, Consultant ParseTree Corp ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Simple(?) dialplan question.
On Sun, Mar 22, 2009 at 4:09 AM, Asterisk aster...@solutionengineers.comwrote:
Hi List,
I have a nice simple dialplan question for you Currently, I have
definitions similar to the following in my extensions.conf file, to allow
me
to dial out using a variety of channels:
; Direct dial (number starts with zero), use 0151 xxx :
exten = _0.,1,Set(CALLERID(number)=0845xxx)
exten = _0.,n,Dial(SIP/${ext...@sipgate,90,t)
exten = _0.,n,Playback(invalid)
exten = _0.,n,Hangup[/code]
(I've munged some of the numbers, hence the x's)
Now, this works fine provided the person answers in 90 seconds or less: If
not, I get that option is invalid announced, and it hangs up. I want to
do
this:
If DIAL fails because the other party is engaged, I'd like Asterisk to
automatically re-try the number, for as long as I've got the handset off
the
hook or until the other party starts ringing. As there'll be no ring tone,
it'd be nice it it could play music until DIAL succeeds in getting a ring
tone; at which point it makes ring ring noises (this will serve as my
prompt that - hopefully - someone's going to answer soon).
If DIAL fails because I got the number wrong, then a PLAYBACK to that
effect
would be useful... I can record my own soundfile if there isn't a standard
one. By wrong, I mean the exchange would return number unavailable, rather
than I get the wrong person!
If DIAL fails after it's been ringing for ages (e.g. when calling the local
Post Office sorting office, who only answer 1 in 5 calls), I'd like it to
retry, ala the busy response.
IF DIAL exits because the other party hung up, I'd want it to simply hang
up
on me like it does now. I suspect this is standard behaviour? But maybe it
tries to read the invalid announce to a closed channel with my dialplan,
I'm
not sure.
If the above can be achieved in extensions.conf, that's great, as I've not
done any AEL... but if AEL (or AGI, even) is the only way, so be it...
You can do it all three ways.
In AEL, you'd do something like this
context internalexten
{
_0. = {
Set(prevstatus=NOANSWER); /* set up a prevstatus */
Set(CALLERID(number)=0845xxx);
while(${prevstatus} == NOANSWER || ${prevstatus} ==
BUSY)
{

Dial doesn't do that. You may have to correct some typos, etc. that I've
made above!
A hangup from the remote end will end the Dial app, and the result should be
ANSWER,
which should drop you out of the loop and end the call.
Also, a hangup from the dialing exten should just terminate the dialplan
execution.
I might note that the above code should be easier to read than the equiv
extenstions.conf
code! But, I guess I'm biased!

It'd be silly timing such, as the CDR records are currently rounded off to whole seconds. My current thinking is to specify exactly which app invocations you want to track; those involved with dialing would be automatically tracked. Or time groups of invocations via forcing a leg-split via a simple dialplan application call... again, read the doc, and let me know what you think. murf -- Steve Murphy ParseTree Corp ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

It's complaining that you don't have Extension: and Priority:

The Channel: lines calls one phone, the Context, Extension, and priority say
what to execute for the other channel,
and the two are bridged.
Whether the context, exten, and priority specified are in an AEL supplied
dialplan or an extensions.conf
dialplan, doesn't matter. You can even mix both together to form a dialplan.
Let's see, I have a call file laying around...
Channel: Sip/snom
Context: workext
Extension: 983075878001
Priority: 1

This will ring the phone specified in Channel, and when it answers, it will
run the extension you specify, and connect the two. (in this case it will
dial the movie hot line in Cody, WY, and the leading 98 says to use
a certain ISP to place the call.

In that scenario, you'd get one CDR for each channel involved in the total call, but the interesting one would be the one with Party=B in this case. CDR: Party: B; channel: A, dstchannel: B, start: When B was dialed; ans: when B answered; end: when B hung up; disposition: ANSWERED. There would also be CDRs for A, C, D, E, F, and G; Each would reflect who called them, when they answered, when they hung up (ended). CDR: Party: A; channel: A, dstchannel: null; start: when A went offhook or submitted call, dep on tech; ans = start time, if applicable; end: when A xferred to C and got dialtone.

I'd imagine you could tell that all but B were internal locations, and B's CDR is probably the only one you'd be interested in billing for in this case, since B is the destination of the call. A would or should foot the bill for the call, no matter how many others talked to B (at least in my opinion). Deciding who's interesting for billing is not Asterisk's job.

I vote to give as much detail in the CDR as possible, that would require ALL Asterisk applications to be CDR AWARE They would have to inherit a few details during the copy. The Current (OLD) channel will be in charge of writing the CDR as it stands at that moment in time to the CDR logger. For example. A calls B, B then transfers (blind) to C, and then C puts me one hold, picks up and transfers me to D. A calls B using Dial() CDR Starts with origin and dest. B Answers B blind transfers to C Dial() started by A dies and is copied to new one started by B. Exiting Dial() should write a CDR record reflecting that call was transferred, and copy needed variables to New Dial() C Answers New Dial() writes to CDR starting CDR for new leg C Places A on Hold. MusicOnHold() will need to log an entry into CDR with UniqueID. C picks up Held call. MusicOnHold() Again writes to the CDR as it exits

Will both fulfil the requirements of CALEA? We're not yet operating in a jurisdiction where CALEA applies. It looks good enough for the jurisdictions we operate in, possibly apart from the transfer issues further down, but I am certainly not a lawyer. It's been proposed that we implement just the Simple CDR now, and it be introduced in some 1.6.x (or higher) release. In that release, the existing CDR system would be deprecated, and in some futurer release the old (now current) CDR system would be dropped entirely. What do you think? Are we high on drugs, or what? I need this functionality for transfers, and I don't think Simple provides it: A calls B: A pays for the whole duration for A = B B transfers to C: B pays for B = C, A is still paying A = B Good Question: Can Simple CDRs be used in xfer situations? Let's take a look. In this particular situation, 3 channels are involved: A, B, and C. Therefore, you will get 3 CDRs.

A's CDR could be used to bill A for his call in. It covers both the time A spent talking to B, and C. If you charge a different rate for A talking to B vs C, then you have some interesting SQL queries to make, I'll guess... C's CDR records that B called C. It doesn't mention that A is doing all the talking. B's CDR records the call from A to B; this is the only one that seems a little useless... Is this enough? If this is all you had, could you make it work? If you can't, would adding a field or two help? If it was A who transferred the call instead: A calls B: A pays for the whole duration for A = B A transfers to C: A pays for A = C, and A is still paying A = B B and C get to talk for free, while A pays twice. In the SImple CDR world, here's what would be produced: CDR1: A start: e1 ans: e1 end: e4 Party: A disp: ANSW linkedID: abc9 CDR2: A - B start: e1a ans: e2 end: e6 Party: B disp: ANSW linkedID: abc9 CDR3: A - C start: e4 ans: e5 end: e6 Party: C disp: ANSW linkedid: abc9 Here, A's total connection time is in CDR1; B with CDR2; C with CDR3. The call from B to C is in CDR3. A's transfer to C is in CDR3 (I just corrected this in the CDRfix2 document). Again, is there enough info here for you to do what you need to do? If not what addition could be added to make it work? This should apply whether transfers are attended (soft), unattended (hard) or caused by SIP redirections before answering. Ideally it should also be possible to simulate SIP-like redirections in the dialplan with the same CDR behaviour.

[asterisk-users] CDR Rewrite -- Questions to the users
Hello! Most are probably bored seeing another letter about this, but I've put in a fair amount work on a spec for rewriting the CDR system in Asterisk, and I have some questions: First, please look at what I've written so far: svn co http://svn.digium.com/svn/asterisk/team/murf/RFCs and look at the file CDRfix2.rfc.txt in the RFCs dir. The spec SIGNIFICANTLY alters the way CDRs are generated, how they are structured, and what they express. If you have ANYTHING to do with CDRs, then it is critical you become involved in the design process for the new system! Or suffer with the results! What's going on? I wrote up two modes of CDR generation: Leg-Based, and Simple. A new field, linkedID, that can be used to link CDRs as part of the same total call. Leg-Based is (or can be) very detailed. Every CDR has a type, like CALL, AXFER, BXFER, PARK, etc. Depending on what actions occur during a call, a call can be split up into several legs. A dialplan func to insert an event that will create a new leg will be available, with its own user-specified type. Simple is just that. One CDR is generated per activated channel. The start time is when it was created. The end time when it died/hungup. The answer time is... you know! No fine-grained details. No dialplan fanciness. linkedID can help you group channels involved in a single 'logical call'. QUESTIONS: Which of the two would you see being useful to you? Is there Yet Another CDR system you would like to see instead? How would/should it work? Will both fulfil the requirements of CALEA? It's been proposed that we implement just the Simple CDR now, and it be introduced in some 1.6.x (or higher) release. In that release, the existing CDR system would be deprecated, and in some futurer release the old (now current) CDR system would be dropped entirely. What do you think?

I don't think the queue_log stuff will need to be modified, at least with respect to CDR's, as all they do is reference the uniqueID... there may be other reasons pertaining to enhancements, etc. that might demand some code update there, but that's not in the realm of CDRs. By tweak their code, is might involve a few lines of update, or a total rewrite, I don't know. But the idea is make the specs for the new system as public and known as possible in advance of a new implementation. The period of time during which the old code would still exist would be an entire release, so that gives you probably about 2 years... in the meantime, we'll probably want to cease maintaining the old code. That should mean that the old code should actually become more stable, because so far, it's very difficult to change ANY aspect of the current CDR system without introducing new regressions. Given the fact that the current implementation has serious problems, holes and gaps wrt to parking, xfers, etc, and is so hard to maintain in its current format, the long-term goals of reducing the cost of maintenance, and getting higher reliability, hopefully will make the effort of recoding worth that effort. murf -- Steve Murphy m...@digium.com Digium smime.p7s Description: S/MIME cryptographic signature ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Again that's mixing fields that shouldn't be. The calldate or starttime can be used to sort the CDRs on creation time. If you're going to call a field uniqueid surely a good effort should be made to make it live up to its name. If it's intended to be a sequenceid then that's what it should be called. Sorry, I apologize for the 'uniqueID' field; I didn't invent it, or name it, and there is little definition for it. I think it's accidental that a transfer could yield two CDRs with the same uniqueID. I'm all for just simply dropping it. Maybe I will. LinkedID on the other hand, is a way to associate 'linked' channels. A linkedID is guaranteed (on the same Asterisk server) to be unique from any other linkedID that has been issued by that server. By appending another string, you can guarantee it is unique across systems. So, if you use a system name, or Asterisk server name, that you yourself guarantee to be unique among all the asterisk servers that would contribute CDRs to a database, you achieve complete, guaranteed uniqueness. If you use instead a 36-byte UUID, you avoid having to invent the unique system names, but the complete uniqueness guarantee is off. The chances of a collision are pretty small, so they are 'practically' useful. But still, to be mathematically precise about it, simple servernames are infinitely more unique than UUIDs. 10^36 is a big number, but infinity is even bigger. and the ratio between the two is infinity. Now, as to splitting the currently per-server unique label from the per-network part of the label, well, I'm dense, I know, but I still don't see any overriding reason to do so. Yeah, it might be cool to call the uuid part of the label a uuid, but really, it's silly. Now you have to use two fields to get uniqueness. Not cool. Just because a DB understands a UUID, doesn't mean you are obligated to separate it. Just because a language has a feature, you are not obligated to rewrite perfectly working code to use it, especially if it obfuscates what is going on, opens the door to bugs, etc. etc. I don't see any reason, either (and I could be missing something really obvious here, I admit), for providing a field that *is* unique to every CDR generated. When the CDR is entered into a table in the db, it occupies a certain row in that database. That row number will be guaranteed to be unique. Since nothing in the Asterisk world references that data once it's written, there would be little purpose in generating it. If you need a unique ID that spans all CDR's ever written to that db, across time and space, even if after a year or so, you prune all the old CDR's from the DB, and allow the row numbers to be reused, then *that* might justify such an ID. (you could search backups or something for that entry, if some customer brings up a problem after a year)... But, if your DB understands uuid's, then can't you automatically generate one for it via an entry in the table definition? And, the linkedid already provided is timestamp based, so across time, it will never be repeated. So, I'm still not seeing any reason why you need to dissect the linkedid field. How it was built doesn't matter, as long as in total, it has the necessary uniqueness property. And here's another thought. I could imagine that, if we appended a system name to the linkedID to guarantee its uniqueness, we might also like to have the system name in the CDR, so we could make queries and see if any of the Asterisk servers are busier than the others, etc. I wouldn't dissect the linkedID to get it; I'd add the system name as another column. But that's just me... If I'm missing something, educate me. I need to understand this sort of stuff to be able to write a useful CDR system. I guess I could simply have used a simple integer for a linkedID, and had a routine somewhat like the one that coughs up the uniqueID's, just use a lock to provide a number that is incremented safely, (atomic_fetchadd_whatever) and hand it out. Then I could have used a numeric comparison. Might be faster. Maybe Someday... But, it is NOT a number. It's got a period in it but uuids usually have dashes. It's a string.

A channel has to have a very clearly defined definition of answer and hangup whereas dial plan applications don't. Hadn't thought along that line before: classifying the *kinds* of Answer.

It doesn't make sense to store an outgoing dial result in the originating channel CDR A single CDR should not be able to cover several Dial attempts or even multiple destinations within the same Dial attempts. If you think of Dial as just another application and of CDRs being designed to reflect the lifetime of a channel then things are simplified. If a Dial or any other dial plan application causes three channels to be created then that's 3 CDRs that will be generated. If the first Dial call fails and another one is made with another 3 destinations than that's another 3 CDRs that will be generated. OK. What if, instead, we record the disposition of the dial in the created channel CDR? A channel comes into existence only once. For external incoming calls into the PBX, the disposition is pretty uninteresting, because we'd not create the channel if the disposition wasn't ANSWERED... (well, at least in the DAHDI world, maybe not so much in the voip world)... but, once asterisk dials B in A's behalf, we could record all the dialing action in the CDR for B; It's src/dest related fields could record the dial from A to B; the disposition would be FAIL/BUSY/NOANSWER/etc... That's not quite true. An incoming call to Asterisk could FAIL due to some dialplan condition, it could go UNANSWERED if the dialplan forwards the call to a destination that does not pick up, it could get CANCELLED by the external party before Asterisk finishes processing etc. Aha! Hadn't thought on these lines... but that's true. Dahdi is fairly binary, but SIP has more possibilities. Oh, and BUSY/NO ANSWER/FAIL for a non-s exten, would also override an ANSWER on exten s, BTW... And, would it be proper to include all dial attempts? My guess is that you would *NOT* want to see any dial attempts in this mode. Well, at least, in this particular case, if A *tries* to dial B, but B doesn't answer, then since A is a live channel, we would record it's life in the system. When A hangs up, we would see the NO ANSWER disposition, and the destination of B, right? If A tried to dial a group, and nobody answered, the destination would be a random member of that group, the args to the Dial command would record the other members, usually. If A tried to dial a group that consisted of 10 members then that's 10 CDRs that should be generated. For those people that don't want unanswered CDRs they can be easily turned off with the configuration option. For those of us that want a CDR for every call which includes successful and unsuccessful call attempts we ge them. OK. It's looking like we are the same wavelength. Let's say you do your examp, but we add exten dev SIP/w to the list for variety; suppose: W just plain doesn't ANSWER X is offline, so it's FAIL; Y gets answered; Z is busy If you have unanswered = yes, then you'd expect to see: 1. A to Asterisk which is answered (by the dialplan) 2. Asterisk to X which is FAIL 3. Asterisk to Y which is answered, 4. Asterisk to Z which is BUSY 5. Asterisk to W which is cancelled But if you have unanswered = no, then I guess you'd just see: 1. A to Asterisk which is answered (by the dialplan), 2. Asterisk to X which is FAIL 3. Asterisk to Y which is answered, 4. Asterisk to Z which is BUSY or would unanswered = no also suppress #2 and #4? I think with unanswered=no the desire would be to exclude any call with billsec=0. The disposition field is a descriptive field and not something that I think should be relied upon too heavily. Different channels may set the disposition field differently for eaxmple the SIP channel could get clever and set it to FAILED - 403 Forbidden to reflect the SIP response code that caused the failure. That description would obviously not make sense

The simplest I can think of is:

adding the quotes just makes it so if ${FOOBAR} evaluates to nothing,
then it will still end being a token, and you avoid the syntax error.
You have to keep in mind that by the time the $[ ... ] exprs are evaluated,
all ${..} constructs have been recursively evaluated away.

If the server name is useful in the CDR then add another field for it. I for one load CDRs to and from a database using a typed langauge and would be utilising the UUID field as a specific UUID type.

Where I and I'm sure others want to use the current uniqueid CDR field is as the primary key in a database. Being able to rely on at least one field in the CDR being unique solves a lot of probelms for billing engines such as if the billing engine stops and starts has a particular call been billed or not. At the moment the uniqueid is next to useless for those of us putting CDRs into a database. As to the 'old' uniqueID, I agree, it was of extremely limited use. Firstly, it was not really unique. In several xfer situations, you would end up with two cdrs that had the same uniqueID, because of the way the the CDRs were transferred during a masquerade, methinks. So you couldn't use it as a 'unique' key -- the row # would be better. And it couldn't really even be used to tie CDRs together in any useful way.

On Fri, 2009-01-09 at 01:53 +, Grey Man wrote: I would be interested in additional information in the CDRs as I'm sure others would. My worry is it's not a critical peice of CDR information and because it sounds like information being generated at the dialplan level it could end up being complicated to implement or confusing to desgin and become a distraction from getting the core CDR fields sorted out. I tend to agree. We were discussing this sort of thing on IRC today, some of us devs, trying to guess what new things users might throw at us as to requirements for the new CDR system(s). I have a feeling that there will ALWAYS be implementers that will have a need for very... interesting pieces of information, and will want to see them in the CDR system. But, there is a userfield, and users can set it in the dialplan. As long as funcs like CHANNEL() can get at the info you'd like to have, then you can always shove that info into the userfield. If CHANNEL() doesn't make a field available, it can easily be expanded. (At the current moment, CEL doesn't carry channel vars into the event data; it seems a pretty wasteful business; perhaps in the future, I can make it so any channel vars starting with cel- would be copied into the event data. In the meantime, copy what info you need into the userfield.) Another customization need would be where CDR's would be split-- what kind of things you want to time. The Simple CDR spec really wouldn't allow any splitting, but the leg based CDR approach would provide a simple call in the dialplan to split a cdr and assign a type to the newly completed CDR. I honestly can't think of any other operations that might need to be done, except attach extra info to a generated CDR; the only question would be when it would be best to attach it; and that's something we have to think about. Before a dial, so the dial event/answer event records it, or just before the channel closes (h exten?) or whatever... In the case of CDR-legs, the timing of when you store info on the channel, determines which leg(s) the info appears on. There are possibly a lot of games that could be played with this. There are/were a few bugs in the tracker that basically were complaining about missing information. In most cases, this was due to the fact that there were two place where data was being stored: on the channel, and in the CDR struct. And there is/was no simple explanation of when the channel information was updated into the CDR struct(s). Well, the new system will have simple rules to allow you to predict when certain info on the channel will be taken to be copied into a CDR. (I hope). Another side-effect of moving the CDR system out of the pbx loop is the fact that the h-exten may or not be the best place to try to add/mod CDR related data any more. I could go on (and on) about the h-exten, (for those of you wondering what the h-exten is, it's the hangup extension in the dialplan; the pbx will execute that extension when the channel is being hung up.)... but I won't.

The continuing discussion on a future Simple CDR mode of generation... from which I will extract the info and add a section to the overall CDR spec I'm developing... For newcomers, Simple CDR mode would not break the conversations into legs at all. Each CDR would simply record the total time spent alive. It would start when the channel got created. It would end, and the CDR get posted, when the channel got hung up and destroyed. It might have been transferred, parked, put on hold a hundred times in the process, but this wouldn't matter.

A disposition of something like CANCELLED could be set for the dial legs that Asterisk cancels after the first one is answered.

A to Asterisk which is answered, 2. Asterisk to X which is cancelled, 3. Asterisk to Y which is answered, 4. Asterisk ti Z which is cancelled. I like the CANCELLED idea another disposition!

Hi murf, To my mind only hangups should generate CDRs and nothing else should. When you say for each channel that did anything I'd like a CDR I'm not to sure about that, if you mean to generate a CDR for every type of channel that is ever hungup then the answer is yes. If you mean to generate a CDR on non-hangup channel events then the answer is no. OK so, if A calls B, B parks A, A's park expires, B is rung, B answers, B xfers A to C, they hang up, we should have a CDR for A's time, with the start time being the time the PBX created the channel for A; the answer time would be (if A is an incoming call) when the PBX answered the incoming call and maybe started giving A the IVR experience, and (if A is an extension), when B answered the call. The end time would be when A was hung up. A CDR for B would be generated? with his answer time when he picked up the phone to answer the incoming call from A? and an end time when he parked A? Another CDR for B would be produced he answered the callback from the PBX for the expired session with A, and end when he got hung up xferring the call to C? Another CDR for C would be produced to record C's conversation with A, start when his phone started ringing, answer when he answered, and end when he hung up? Am I on the right track? I don't use Parking myself so my understanding may be slightly off but from what I do understand of Parking the CDRs would not be generated quite how you describe. The main point is that Parking a call should not generate a CDR as the Park operation has not necessarily ended a call. Parking a call will hang you up, in most normal cases. This includes calling the Park() app, bxfer to the parking exten, and using the one-touch parking features. But, if some strange combo of events allows someone to park without a hangup, then I'd agree, no CDR should be generated. In your description I think the CDRs should be: 1 The call from A to the PBX, start time when B answers, end time when the A-C call is hungup, Can't do this; it would be inaccurate; start time is when A either picks up the phone (if dahdi exten), or when A submits an invite (if sip exten), or when an incoming call (via sip invite, or dahdi fxo i/f) arrives at the pbx. As to Answers, we have to start getting pedantic; if A is an exten, then the first answer will be when B answers. But if A is an incoming call via, say a dahdi fxo interface, or an incoming sip invite, then an s exten is going to get run, and usually the PBX runs the answer() app, and this will usually be the first answer.

Yes, I do! I was concerned that users were falling into a common
error, where they forget to wrap variable references in $(); so,
if it looks like an expr has arithmetic operators, but no variable
refs, then you get this message.
Yes, I *could* have made it more intelligent. File a bug, and I'll
see if I can do so. At the worst, you can ignore this warning, or
I can simply remove this overly-simple warning.

Call billing only really needs the start and finish (like we get now) - but proper call logging requires all steps. Do we leave CDR's as they are (for billing purposes) and have a separate 'event' driven log for call logging? Or do we change the CDR structure to accommodate logging as well? Personally, a separate 'event' log seems preferable to me as this keeps existing billing platforms useable. It just means the logging programs will need to be re-written to look at a new database for events. I know we have the AMI - but that puts out a lot more information than is needed for simple logging (and requires something to prune and store the events in a database of some sort). That's the classic tradeoff... too much vs. too little detail. If you want 3 tons of detail, use Manager. If you want just 1 ton of detail, use CEL If you want a half-ton of detail, with time diffs built in, use CDR. There are some other differentiating factors... like the fact that CDRs do provide some grouping of events natural to billing. At any rate, NONE of them can be directly used for a billing app (if any currently can, you may have a problem!) --and I've seen folks use hybrid mixtures of the above to put together The Perfect Billing System. murf Any thoughts?

I couldn't disagree more. The CDRs is the MOST reliable source for billing purposes (in postpaid mode that is - for prepaid you have to use something else (although even then the CDRs can be helpful for consistency checks)). Other alternatives (e.g. radius) could not give you the same level of consistency as the CDRs (although better than other implementations because the gateway retries to send the packet many times before giving up). What would happen if your radius server was overloaded and could not process accounting packets for a few secs/mins/hours? What would happen if the network is down (and the event processing handler is in another box)? All these calls would be lost. This can rarely be seen with CDRs logging. Because, whatever might happen you can always count on them to rectify the situation. I think the same can be said about other event based billing setups. The gateway itself cannot (and shouldn't really) be aware if the event was successfully processed by the handling back-end so you end up with inconsistent data and lost calls. Now, a combination of the two (e.g. radius+CDRs) can cover all the possible gone-wrong scenarios. But in order for that to work you need all the detailing you can get in the CDR. If ,however, you don't want to load your gateway with complex CDRs you could entirely turn them off (or parts of it e.g. b-leg logging, log only a few details etc). Well, if we spec some options, and it doesn't get *too* out of control, we can spell out a few different scenarios for the generated CDR's. Greyman's just wanting to know how long A was connected, how long B, etc, is an entirely different approach than spelling out each leg. Dropping stuff like HOLD and PARKING is possible, too.

I've been ruminating over Greyman's suggestion about simplified CDR's for the past few days, stepped outside my 'box', and I think realized what he actually was asking for, at last. As to the event system, say no more. CEL is it. It will spew out all possible CDR related events in any of several formats, in somewhat real-time (as they occur) order. The state of the channels are included with the time of each event. But, this alone isn't really useful in a database. Try coming up with SQL queries that tell you useful things about what's happened, or happening... CDR format is useful that way; and, like Brian, yes, you can mix the two to your heart's content, even add manager events to the mix. murf Cheers Andy -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Grey Man Sent: 05 December 2008 09:37 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] CDR Design On Fri, Dec 5, 2008 at 8:26 AM, Andrew Thomas [EMAIL PROTECTED] wrote: In summary: Leave CDR exactly as it is and create a new CEL (Call Event Logging) module (optional in modules.conf) that puts out (and does not accept) call event information (ie. a one-way fire-and-forget output from Asterisk).

Sure, there's going to be some simple bits to it, but as in every system with a fair number of event types, exceptions to rules, etc., it's going to involve some serious thinking, blood, sweat and tears. The code will encapsulate some hard-earned experience, minus some false assumptions that had to be corrected. Now, it might end up being a walk in the park, and maybe I'm just being pessimistic, but personally, as a programmer, a CDR spec is going to be easier to bill from than a sequence of interlaced events. murf ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users -- Steve Murphy Software Developer Digium smime.p7s Description: S/MIME cryptographic signature ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

The more convoluted any new design gets the less chance it has of ever getting implemented in the near future. Getting a basic accurate CDR system in place does not preclude future enhancements but without it they'll just add another few layers to the house of cards.

Regards, Greyman. P.S. Sorry about the duplicate post. I actually sent the email to the list 4 times with around 8 hour spacings and I'm not sure why there was a problem getting it through. Everyone-- I've just made some major changes to the CDRfix2.rfc.txt file in http://svn.digium.com/svn/asterisk/team/murf/RFCs to accommodate the Leg approach instead of a channel-based approach. Greyman is correct. By cutting the timeline into legs, we avoid all the nasty channel state problems, or so it appears thus far. I threw out all the text about channel/peer state, fleshed in all the example cases, etc. I added a section describing the linkedID field. I provide a list of CDR record types at the end, that will eventually be expanded to describe each field that set in that type, and what they mean. The types so far are: 3WAY AXFER AXFER1 AXFER2 BARGE BXFER CALL CONF HOLD PARK RECALL RECONN USER WHISPER murf -- Steve Murphy Software Developer Digium smime.p7s Description: S/MIME cryptographic signature ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

OK, Greyman, your logic is solid. If we provide a CDR implementation that just generates the individual call legs, and ties them together via the linkedid (see team/group/newcdr), then both camps should be able to derive the info they need for billing, via hopefully not-overly-complex SQL queries to a backend db. I'll modify my RFC to reflect this line of thinking. Yes, it is a bit of shift. And, yes, the implementation will make this new approach optional, and not default. But, pardon if I make it available via the CEL domain come implementation time. It should take me a week to rehash my document; perhaps longer (I'm in bugfix mode, and this borderline development work); in the meantime, those with decided CDR needs might make their wishes known, if they do not think this approach will work. Speak now, or forever hold your peace; or forever complain... or whatever. If this is particularly distressing to you, perhaps your fears might be slightly assuaged when you read the details... I was part of a team that did design a multiservice billing system about 15 years ago and the solution people seems to agree on here (and me to) looks pretty much the same i.e one call may consist of several calls legs. In addition to the linkedid it would be nice to have an indication in the cdr that tells us that 'this is the lastone on this linked id'. Our experience was that we shouldn't for load reasons work with cdr's in the immidiate multileg format in the DB. So we did collect cdr's in a tmp DB until we got the the record with end marker set. We would then produce our final cdr for the actual service, store it in billing col. and delete it from the multileg col. When a new service is created we only have to make a the new customized cdr, we don't have to touch the generation of the multileg format. Freddi Freddi-- Very interesting. Brian Degenhardt had some code we just gave some thought to, wherein we determine if the last channel involved in a linkedID set has been closed. If so, then the entire set is finished. We can use this facility to get you a closing attribute, that could be added to the last CDR emmitted for that set; OR, we could just emit another CDR with type CLOSE or FINAL or something, that signals the end of the chain. murf -- Steve Murphy Software Developer Digium smime.p7s Description: S/MIME cryptographic signature ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Call it Enhanced CEL or something like that. Why?: because otherwise you will forever get arguments about it. Traditionally, a CDR is one line per call; all inclusive. And as you know, that is a horrible standard for todays complex systems; but it is what it is. So, perhaps Asterisk should not build native CDR at all. It should build your Enhanced CEL. A separate perl/ruby/etc script could be included in the Asterisk distribution that build the CDRs after the fact. Or multiple CDR scripts based on the flavor-of-the-day of what CDR means. Just my thoughts. I very much look forward to your code. This will make my life so much easier. John John-- Point well taken, but if I call it anything but CDR, people will go Huh?. CEL is per-event, but CDR's are event-groups. I think we are safe to keep calling it CDR, because I perceive that at least some of the big-name pbx vendors are generating much more than simple line-per-call records and they still call them CDR's. Using a db to make sense of CEL events for billing purposes is extraordinarily difficult, as the strings of events are reported as they occur, and with multiple calls going on simultaneously, the events are interlaced. You can pull out single threads by sorting on the linkedid; but still you have strings of events among multiple channels that will not be obviously easy to decode, especially by concocting SQL queries. Thus, the need to provide some sense via CDR's. And, yes, I agree with you. I will try to make it so a CEL-CDR generator could be run either 'real time' inside asterisk (via make menuselect choice), (and using your selection of existing backends), AND, I can try to provide a stand-alone option that could be run on CEL events that were logged to one of the CEL backends; probably just one of the plain-text ones. murf -- Steve Murphy Software Developer Digium smime.p7s Description: S/MIME cryptographic signature ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
